PbS Quantum Dot / ZnO Nanowires Hybrid Test Structures for Infrared Photodetector

Abstract

Aiming at developing infrared optoelectronic devices compatible with silicon-based large scale integration, we investigated performance of PbS colloidal quantum dot-silicon photodetectors using several different test structures. Silicon-based IR photo detector structures composed of PbS quantum dot / ZnO nanowire were investigated.
